2. Poultry Disease Prevention and
Control for Small Flock Owners
By Allah dad Khan

3. BIOSECURITY FOR POULTRY
Commercial flocks and small flocks:
Use same techniques to prevent
disease
Same diseases threaten both

4. Objectives:
• Disease prevention through effective
biosecurity practices- keep diseases
out!
• If breakdown in biosecurity and disease
challenge occurs, ensure chickens are
immune competent to limit losses

5. Disease organisms get to other farms by one
of the above ways 90% of the time. Break
the cycle!

LPAI to HPAI, common,
vaccination may be practiced in
some situations

34. Conclusions
Take home message:
Goal: to prevent entry of diseases into your
flocks by use of biosecurity practices
Plan: develop and implement a common
sense disease prevention program
